根因分析

使用了未在 pytest.ini/pyproject.toml 注册的自定义标记；pytest 发出警告，在 `-W error` 下变为失败。

English

A custom marker is used without being registered in pytest.ini/pyproject.toml; pytest emits a warning, and with `-W error` it becomes a failure.

解决方案

  1. 98% 成功率 
    # pyproject.toml
[tool.pytest.ini_options]
markers = [
  "slow: marks tests as slow",
  "integration: requires external services",
]

# then
pytest -m slow
  2. 90% 成功率 
    # pyproject.toml
[tool.pytest.ini_options]
addopts = "--strict-markers"
markers = ["slow: slow tests"]

无效尝试

常见但无效的做法:

  1. 90% 失败

    Changes test semantics (skips instead of conditionally selecting) and loses filtering capability.

  2. 70% 失败

    Hides typos in marker names and prevents `--strict-markers` from catching regressions.

  3. 95% 失败

    Suppresses all warnings, including real deprecations and correctness issues.
